Abstract
The invention discloses a recap rubber for a segmented mould and a production process thereof. In the recap rubber, carbon blacks N234 and N330 which have higher wearability are adopted to improve the wearability of tread rubber, and 30 parts by weight of natural rubber are adopted to reduce the cost of ingredients and the tread rubber so as to ensure that the recap rubber is more competitive in the market. In the production process disclosed by the invention, two-section thin-pass plastication which is carried out 12 times and a thin-pass mixing method are adopted to improve the uniformity and the physical properties of the tread rubber.
Description
Technical field
The present invention relates to a kind of tread rubber and production technique thereof of old tire renovation usefulness, especially a kind of segmented mold renovates the tread rubber and the production technique thereof of usefulness with old tire.
Background technology
China's renovated tyre the earliest are with aluminium-making mould old tire to be carried out heat to turn over and add the top and handle, and at present, main what adopt is the cold technology of turning over, and promptly carries out the cold processing of turning over vulcanizing boiler.Present vulcanizing boiler can vulcanize 6～24 for every jar, mainly be to add to knock over new processing, if but the sidewall goes wrong, this method can not solve, the tire top is also bad with combining of sidewall in addition, and there is potential safety hazard in fracture easily, domestic afterwards employing segmented mold renovates processing to old tire comprehensively, has solved the sidewall problem.Tread rubber is the main materials of renovated tyre, the quality of tread rubber directly determines the effect of old tire renovation, and at present, the sulphur that adopts in traditional tread glue formula is general sulphur, the easy bloom of this sulphur, the DZ and the easy bin cure of PZ cryogenic vulcanization that adopt, the wear resisting property of the carbon black 220 of employing is poor, and machine oil easily infilters in the rubber, the finished product tread rubber quality of producing is crisp, the poor toughness of product is prone to the slag phenomenon in the use, there is potential safety hazard in vehicle in moving process.At present, plasticate natural gum and directly using of Banbury mixer of no use in the pre-vulcanization process of tread rubber, this kind technology is not given full play to the leading role of natural gum in tyre surface.
Summary of the invention
Technical problem to be solved by this invention provides a kind of segmented mold superior in quality, with low cost and renovates the tread glue formula of usefulness and a kind of segmented mold tread rubber production technique of giving full play to the leading role of natural gum in tyre surface is provided with old tire.
In order to solve the technical problem of above-mentioned prescription, the invention provides a kind of segmented mold and form by the raw material of following mass parts ratio with the glue that recaps:
Further, used anti-aging agent is made up of the raw material of following mass parts ratio:
4010 0.27
RD 0.74
Paraffin 0.8.
Further, used tackiness agent is made up of the raw material of following mass parts ratio;
Gu horse grand 2.65
Aromatic hydrocarbon oil 4.3.
Further, used promotor is made up of the raw material of following mass parts ratio;
CZ 0.3
DM 0.23
Insoluble sulfur 1.
In order to solve the technical problem of above-mentioned technology, the invention provides a kind of production technique of using tread rubber processing segmented mold of the present invention with tread rubber, this segmented mold is made up of following steps with the production technique of tread rubber:
Step 1, natural gum is carried out two sections with refiner plasticate, plasticating for every section will be natural gum thin-pass 10～12 times, wherein one section plasticate with two sections plasticate be spaced apart 20～24 hours;
Step 2, various mixtures are joined in the natural gum after plasticating, in Banbury mixer, carry out mixing;
Step 3, the rubber after mixing in the step 2 is added sulphur in mill, play three bag processing;
Step 4, with the cooling of the rubber after the step 3 packing 20～24 hours;
Step 5, with cooled rubber heating in the step 4, press soft back automatically transporting materials to extruder for shaping with mill.
Further, the compounding process in the described step 2 is to adopt the mixing method of thin-pass.
Beneficial effect of the present invention is:
1, adopted scorch retarder CTP to improve the banburying effect in the present invention's prescription, improved the quality of tread rubber at Banbury mixer; The present invention fills a prescription and has reduced the cost of tread rubber, and improves the quality of tread rubber.
2, adopt two sections methods of plasticating to give full play to the effect of natural rubber in the technical solution of the present invention, and adopt the mixing method of thin-pass, improved the physicals of tread rubber at Banbury mixer.
Embodiment
Below in conjunction with embodiment technical solution of the present invention is described in further detail.
Segmented mold of the present invention has adopted the raw material of following mass parts ratio to form with the glue that recaps:
Adopt tread rubber production technique of the present invention as described below: step 1, natural gum is carried out two sections with refiner plasticate, plasticating for every section will be natural gum thin-pass 11 times, wherein one section plasticate with two sections plasticate be spaced apart 22 hours; Step 2, various mixtures are joined in the natural gum after plasticating, in Banbury mixer, adopt the mixing method of thin-pass to carry out mixing; Step 3, the rubber after mixing in the step 2 is added sulphur in mill, play three bag processing; Step 4, with the cooling of the rubber after the step 3 packing 23 hours; Step 5, with cooled rubber heating in the step 4, press soft back automatically transporting materials to extruder for shaping with mill.
Adopt the tread rubber excellent property that prescription of the present invention and production technique are produced, concrete tread rubber Physical Experiment is reported as follows:
The invention is not restricted to the described scope of above-mentioned embodiment, every conspicuous technology distortion of being done according to the technology of the present invention principle all drops within protection scope of the present invention.
